JBPM 4.0 - Missing Class JpdlExecution

[rams.rapol]

Hi,

After i took the latest JBPM 4.0, noticed the below error.
With CR1, the same test case was running fine.

Caused by: org.hibernate.MappingException: proxy class not found: org.jbpm.jpdl.internal.model.JpdlExecution

It fails why trying to load jbpm.jpdl.hbm.xml which has

<subclass name="org.jbpm.jpdl.internal.model.JpdlExecution"
 extends="org.jbpm.pvm.internal.model.ExecutionImpl"
 discriminator-value="jpdl">

Where did the class go? May be my eyes need a checkup...

Thanks

jbpm.hibernate.cfg.xml in the examples folder does not have a reference to the hbm file that you mentioned, so looks like it might be something that is there, but not being used?

[rams.rapol]

yup, removing it works. Only thing is it still being shipped under src directory.

Hi folks,

unfortunately I have the same problem. So, did you remove
the file jbpm.jdpl.hbm.xml containing this bad entity link or any other file?

Another work around seems to be the following: copy the missing class
org.jbpm.pvm.internal.model.ExecutionImpl from the old 4.0RC1-jar to the newer one.

The jbpm.jpdl.hbm.xml file should be deleted, the JpdlExecution class has been removed from 4.0.
